You might think that the Detroit Truetrac vs. Locker is a simple question. It would be, except that one of these options requires you to choose between two things: love and money. Both are essential commodities, so it is not easy to decide between them.
Comparing Detroit truetrack vs. Locker is no different from comparing apples to oranges. They’re both different, and if you try to compare them blindly, you’ll miss many important details that could make a significant difference when choosing one over the other.
Detroit Truetrac and Locker are two types of differential gearboxes that have been around for a long time. These differential mechanisms are commonly used in off-road vehicles. These differentials allow the vehicle to spin each wheel of a powered axle while transferring torque to both wheels of an unmoving axle. There’s a growing interest in these gears with more off-road power today. There are some advantages and disadvantages to both of these differentials, and it mainly depends on the driving styles of the owner as to what vehicle is better suited for each.
Today, we will be reviewing the Detroit Truetrac differential, and standing next to it is its brother-from-another-mother — the Locker (or Locker). Before talking about them, please tell me: Have you heard about these devices?
What is Detroit Truetrac?
The Detroit Truetrac, made by Eaton, is a helical gear differential with no clutches or plates. The planetary design and worm gears transmit torque between the side gears, which means there will be no reaction to axial thrust on the side gears. This part is most commonly used for high-performance streetcars and light trucks but can also handle professional racing. Because it’s a helical gear differential, it has low operating torque, allowing it to have a smooth operation that won’t be noticeable when cruising down the road. It also has a unique feature: as one wheel tries to speed up due to traction loss, the Truetrac transfers torque (up to 100%) from that wheel to the other wheel that has traction.
When looking for a locking differential, the Detroit Truetrac is one of the most popular choices. It is a helical gear-based limited-slip differential, which means that it uses gears to limit wheel spin. Let’s look at this type of diff and find out if it is the best choice for your vehicle.
The following are some advantages of the Detroit Truetrac:
- Decent traction in all conditions (wet, dry, off-road)
- Ideal for vehicles with aggressive tires
- Transfers torque from slipping wheels to wheels with traction
- It helps increase vehicle stability
- Smooth operation
- No maintenance is required
The following are some Disadvantages of the Detroit Truetrac:
- It lacks the anti-spin feature
- It’s expensive compared to other types available today.
- Less traction than a locker or spool on slick surfaces
- No lockout capability
What is a Locker?
A locking differential is a type of differential that allows both wheels to receive power simultaneously. This can be very helpful in off-road situations where one wheel might lose traction. The best lockers will enable you to choose when the power gets locked into both wheels and which ones receive it.
A locker is a differential that provides variable drive torque to each wheel. When the Locker is engaged, it will allow both wheels to rotate at the same speed regardless of whether they are moving in the same direction or in opposite directions. In other words, when you lock your front axle, both wheels will turn at the same speed and ignore any slip difference between them. This lets you go over obstacles that would otherwise cause the vehicle to lose traction and slide out of control.
Detroit Locker is an auto-locking differential that uses a ratcheting mechanism to lock and unlock the differential. It is designed for off-road use and provides increased traction when driving on loose or uneven surfaces. The locking mechanism is engaged when the vehicle is driven in a straight line and is disengaged when the car turns. This allows the car to maintain traction while driving on slippery or uneven surfaces and prevents the wheels from slipping or sliding.
The following are some advantages of the Detroit Locker:
- Allows you to drive on steep inclines without slipping or spinning out
- Allows you to climb rocks and other obstacles without damaging your tires or breakage issues
- Allows for better handling and stability in off-road situations
- Increases traction for better acceleration when driving on slippery surfaces like snow or mud
- A reduction in wheel hop during acceleration or braking
- Improved handling characteristics
- It allows you to get more traction from your tires
- You can use more power to accelerate without spinning out
- It makes your truck more fun to drive off-road
The following are some Disadvantages of the Detroit Truetrac:
- The Locker can be noisy on the road (especially on hard turns & when engaging and disengaging)
- It can be jarring when engaged on the pavement.
- This can be a bit of a distraction when driving.
- Detroit Lockers can be challenging to install, especially if you are not experienced.
- It’s not very good at turning corners. The inside wheel can go faster than the outside during cornering or turning.
